I did set up a new user.
Deleted Umaporn before with all her credentials. There is a bug in IFS since the last update not sure how they determine who is logged in.
The only chance is to re-install everything including Windows. We will lose around 2 man days working time.
Since there may be always changes required, this laptop will be named office2. No spaces and nothing!
User for IFS and CRM also office2.
